- Describe how to construct frequency distribution for qualitative (nominal) data?The term observed frequency refers to____ the frequencies that are hypothesized for population being examined the frequency found in the population being examined the frequency found in the sample dataThe Gallup Organization regularly surveys adult Americans regarding their commute time to work. In addition, they administer a Well-Being Survey. According to the Gallup Organization, “The Gallup-Healthways Well-Being Index Composite Score is comprised of six sub-indices: Life Evaluation, Emotional Health, Physical Health, Healthy Behavior, Work Environment and Basic Access.” A complete description of this index can be found at http://www.well-beingindex.com/ (Links to an external site.)
